Abstract
The utility model relates to a pile clamping device for a hydraulic piling machine, which comprises a hydraulic cylinder 1 and a pile clamping board 2. The utility model has the structural characteristics that the piston rod 3 of the hydraulic cylinder 1 is fixed as a fixing piece on a supporting base 4; the cylinder 5 of the hydraulic cylinder 1 is a move part, and the end portion of the cylinder is connected with the pile clamping board 2; the dubbing input end of the hydraulic cylinder 1 is connected with the output end of the lubricant pump, and the control end of the hydraulic cylinder is connected with a change-over valve; the hydraulic cylinder is provided with two inner cavities, namely, cavity A and cavity B; the cylinder 5 motivates the pile clamping board to hold pipe piles. The utility model is directly connected with the pile clamping board, taking the piston rod of the hydraulic cylinder as a fixing piece, and the cylinder as a move part; the cylinder support replaces the piston rod support of the hydraulic cylinder, on one hand, which can avoid using huge steel cast, bring convenience for manufacturing, and cut down the cost, on the other hand, high strength bolts are omitted; thus the cost is cut down and occurrences of breaking accident and unnecessary damage caused by disproportionate stress of each bolt are avoided.
Description
Affiliated technical field
The utility model relates to fluid pressure type pile press pile chuck, is applicable to the fluid pressure type pile press.Belong to technical field of hydraulic.
Background technology
At present, pile driver is used widely in construction work.Pile driver is when piling, and is generally with pile chuck that stake is stable.The design feature of the pile chuck of prior art is: be fixed on the steel-casting with the cylinder barrel of bolt with oil cylinder, piston rod is connected with folder stake plate, promotes folder stake plate by piston rod pile tube is clamped.There is following shortcoming in the pile chuck of this structure: because the reaction force of pile locking force is passed to bolt on the framework by cylinder tube, make this bolt strained, and bolton is on the framework that steel-casting is made, in folder stake process, if the pretension degree varies of each bolt causes, will make each bolt strained inequality and rupture, and then cause by a folder stake tracheal rupture.Such case often takes place in the reality construction.
The utility model content
The utility model technical issues that need to address are the shortcomings of easily being pressed from both sides the stake tracheal rupture for the pile chuck that overcomes prior art, and fluid pressure type pile press pile chuck is provided.
Technical problem of the present utility model can solve by taking following measure: fluid pressure type pile press pile chuck, comprise oil cylinder, folder stake plate, its design feature is: the piston rod of oil cylinder is fixed on the bearing as fixture, the cylinder barrel of oil cylinder is connected with folder stake plate as moving member, its end, output, control end that the fluid input of oil cylinder connects oil pump connect reversal valve, are provided with A chamber, two inner chambers in B chamber in the oil cylinder; Promote folder stake plate holder tightly by the clamp stake by cylinder barrel.
Because piston rod is connected with cylinder tube movably, the end of cylinder tube is connected with a folder stake plate, and therefore, when oil cylinder input hydraulic oil, piston rod promotion cylinder tube moves forward, and the cylinder tube promotion is pressed from both sides a plate pile tube is clamped.
Technical problem of the present utility model also can solve by taking following measure:
Cylinder tube is provided with bulb, couples together by bulb folder stake plate with the junction of folder stake plate.
Described bearing is the circular steel member.Piston rod and piston are structure as a whole.
The utlity model has following outstanding effect:
1, outstanding advantage of the present utility model and effect are that piston rod with oil cylinder is as fixture, directly be connected cylinder barrel as moving member with a folder plate, oil cylinder changes cylinder barrel and is supported for the piston rod support, can avoid using large-scale steel casting on the one hand, it is low conveniently to make, reduce cost, omitted high-strength bolt on the other hand, can reduce cost and avoid owing to each bolt strained inequality fracture accident takes place, causes unnecessary loss.
2,, therefore, install and use and easy to maintenance owing to omitted the high-strength bolt connection.
3, owing to being that cylinder barrel is rotary mobile, therefore, the power that is applied to folder stake plate also is revolving force, pile tube is held more fastening and is difficult for generation press from both sides stake plate unbalance stress and explosion.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the pile chuck of prior art.
The specific embodiment
As can be seen from Figure 1, present embodiment is made of oil cylinder 1, folder stake plate 2, bearing 4.The piston rod 3 of oil cylinder 1 is fixed on the bearing 4 as fixture, the cylinder barrel 5 of oil cylinder 1 is connected with folder stake plate 2 as moving member, its end, output, control end that the fluid input of oil cylinder 1 connects oil pump connect reversal valve, are provided with A chamber, two inner chambers in B chamber in the oil cylinder 1.
In the present embodiment: cylinder tube 5 is provided with bulb 6, couples together by bulb 6 folder stake plates 2 with the junction of folder stake plate 2.Bearing 4 is the circular steel member.Piston rod 3 is structure as a whole with piston.
Operating principle of the present utility model is as follows: during use, act on one simultaneously by in the clamp stake by several pile chucks, promote folder stake plate holder tightly by the clamp stake by cylinder barrel 5.
The operation reversing control valve, the hydraulic oil that oil pump produces enters in the B chamber of oil cylinder 1, A chamber oil extraction this moment.Because it is inactive that piston rod 3 is fixed on the bearing 4, so cylinder barrel 5 moves to folder stake plate 2 directions, and oil cylinder 1 promoted cylinder barrel 5 and move forward together with a folder stake plate under the effect of hydraulic oil this moment, when each folder plate 2 and pile tube pile tube was clamped.When handling the reversal valve commutation, hydraulic oil enters the A chamber, the oil extraction of B chamber, and cylinder barrel 5 is to the direction motion away from folder stake plate 2, and at this moment, folder stake plate unclamps pile tube, returns original position.
As can be seen from Figure 2, the action principle of the pile chuck of prior art is: pile chuck is when pressing from both sides stake, and its pile locking force is by piston 7 transfer piston rod 3, is delivered to folder stake plate 2 then and will be in the middle stake pipe 8 of clamping plate to clamp.When cylinder tube 5 is subjected to the reaction force of stake pipe 8, this reaction force is passed on the bolt 9 of framework, makes this bolt 9 stressed, in folder stake process, owing to be difficult to accomplish that the pretension degree of each bolt is consistent, the discontinuity of each bolt 9, and bolt 9 is fixed on the steel member 10, therefore, as easy as rolling off a log and rupture, and then cause by folder stake tracheal rupture, causing economic loss, serious meeting causes casualties.
